Simulated Launches - directional, a local view

No, I cannot explain how to use TLE's to determine rocket position during 
launch phase.  What I can do is run STS-PLUS Version 9517 which has a 
Shuttle launch simulator (see STSPLUS Doc p 59).  Dave Ransom makes it very 
clear that this model is only good for the Shuttle launched from the Cape 
and that the prelaunch TLE's and launch time must match.

It would be interesting to know more about how his model works. Maybe fancy 
polynomial substitution for the  physics?

Can you explain how to use TLEs to determine rocket position during
launch phase?
